As the world increasingly goes digital, information security is becoming particularly important. Quantum cryptography in principle can provide unconditional security for quantum communications with the guarantee of quantum mechanics and Shannon's information theory. There exists strong incentive to introduce quantum cryptography and quantum networks into many areas of human society, ranging from field optical network to satellite communications. To extend its applicability and reliability, it is important to develop operable technologies that meet the requirements of secure and low noise coding for quantum state preparation, of efficient and robust controlling technique for key rate extraction, and of scalable and low-cost production for wide deployments. So the purpose of this session, "Quantum Cryptography and Quantum Networks", is to to explore and present various technologies that can be integrated into quantum cryptosystems and quantum networks. Topics to be covered include, but are not limited to, quantum key distribution, quantum cryptography, quantum networks, quantum hacking and defense, quantum optics, quantum measurements, and quantum control.
